I'll brush the dust and hit the high voltage capacitor. Should the metal be all right? A brush is made of wood and won't conduct electricity And where does the fan drop the oil?
As long as the power is disconnected, nothing is wrong. There may be electricity in the filter capacitor, but there is no danger of direct current.The paper film is opened behind the power fan, which can be filled with oil.
Brush capacitor is fine, but to light brush, can not be hard to pull, the fan at the edge of the axis of drip oil, so that it flows along the shaft, to be patient, after the drop, remember to wipe the excess oil
After power cuts, power is removed without any danger. Remember to disconnect the power after 5 minutes to ensure that the capacitors in the power supply are fully discharged. Of course not conductive brush wood, you hand to touch the high voltage power capacitors are no problem.Fan refueling: remove the 4 fixed screws of the fan, the middle of the sticker ripped, you can see a rubber stopper, take off, you can refuel. Some fans do not have rubber plugs, tear off stickers can refuel, grease is best to use viscous oil, liquid will not take long. Can not find the grease for the bearings, then you can find some bike repair butter, to pick a thin one.
1, the power rating is large enough, if the future of a group of dual graphics card needs, the power is best to choose more than 600W rated.2, choose a good brand, such as the Great Wall.3, the interface is enough. Depending on your hardware, see if 6pin's graphics card interface is needed (some graphics cards or even two). If the power does not exist, you have to use the switch head, trouble), the SATA interface is enough, and so on.4, other aspects, what RoHS certification, 80% efficiency, and so on, for ordinary users, is not particularly important.
